Can you describe the code you’re using to do this? I assume you end up creating a TCP socket between the two hosts, and that will send data reliably. If you’re losing data, you may not be writing or reading the data correctly. You can look at Apple’s CocoaEcho sample code to see how to implement TCP data communications. Or at a higher level, I wrote a whole framework to make this kind of stuff easier: <http://bitbucket.org/snej/mynetwork>. —Jens
